If the length of an arc intercepted by a central angle of 1.25 radians is 32 inches, which proportion could be used to find the radius of the circle?
1.25/2π = 32/πr^2
1.25/360 = 2πr/32
1.25/2π = 2πr/32
1.25/2π = 32/2πr

Option 4: 1.25/2π = 32/2πr
Step-by-step explanation:
Arc length = (theta/2pi) × 2pi × r
32 = (1.25/2pi) × 2pi × r
1.25/2pi = 32/(2pi × r)
